With high live feed costs for fish larvae in marine aquaculture, much effort has gone into replacing live feeds with inert microdiets. The ingestion and breakdown of carrageenan and alginate microdiets in Senegalese sole, post-larvae, were discussed at Aquacul…

US feed grain production estimates have been lowered for 2011/12, according to Tom Capehart and Edward Allen in the latest report from the USDA Economic Research Service.

The 30 September Grain Stocks report issued by USDAs National Agricultural Statistics Service (NASS) showed sharply higher-than-expected 1 September stocks for corn.

A 22-month trial with Atlantic salmon in a commercial scale farm in Norway demonstrated the practicality of using feed with low levels of marine protein. The trial followed a complete generation of salmon from smolt to harvest.

The US corn yield has dropped and this is expected to boost prices, according to the USDA Economic Research Service.

Mycotoxin analysis results for the second quarter of 2011 from Biomin, including more than 2,800 analyses of more than 800 animal feed ingredients. At least one mycotoxin was found in 90 per cent of the samples.

High ingredient prices in 2008 led feed mills to begin to manufacture new, less expensive feed formulationsuntested under commercial catfish farming conditions. New feed formulations have been tested at University of Arkansas Pine Bluff for the past three year…

Lower projected yields have reduced global production prospects, according to the latest report from the USDA Economic Research Service.

Even though lupine seeds are rich in proteins, their use in fish feed has been limited partly because of the bitter taste and lack of knowledge about how high a level of lupine the fish tolerates. These challenges have been dealt with in a new doctoral thesis …

Biomin look at minimising the risk of mycotoxins in aquaculture feeds.

Mycotoxin risk management tool involves both the elimination of mycotoxins by adsorptive materials, and the conversion of their toxic structures into non-toxic, harmless metabolites, according to BIOMIN.
